Throwing my hands up on this ignition!

I did.....how they do it? CDI supposed to send ~450V to the coil when running. When its ON but not running, there is no switching (dumping of 450V capacitor voltage) so IIRC you may have little to no voltage to the coil. Use an alligator clip on the switched power line to battery + to ensure your start/run voltage is stable and not loose as AJ stated.

Also noteworthy is the fact that to see an ignition spark 400 times per second would take some seriously sophisticated equipment and cameras. The human eye could never see that. It would look like one continuous spark. And for all intents and purposes it is. It would be nice if Pertronix had some video of that and made it public. If they could do that and prove their claims, they’d sell a kajillion of those boxes overnight.
